Overview
EN ISO 17652-1:2003 - "Welding - Test for shop primers in relation to welding and allied processes - Part 1: General requirements" defines the standardized framework for assessing how shop primers (prefabrication primers) affect the weldability and related processing of steel. Published by CEN/ISO, this Part 1 provides general requirements, terminology and guidance used when testing primers for development, quality control, supplier declarations, contractual references and customer acceptance testing.
Key topics and requirements
- Scope and purpose: Standardised conditions for assessing shop primers on weldability of steel (see clause 1). Intended uses include supplier R&D, production QC, declarations, contractual reference and customer acceptance.
- Terms and definitions: Clear definitions for key concepts such as shop primer, rating test, weldability test, emission test, test of cutting properties and supplier’s recommendation (clause 3).
- Guidance on application: Clause 4 explains how to reference appropriate parts of EN ISO 17652 depending on the test objective - e.g., rating comparisons, weldability testing in production, or thermal cutting assessment.
- Health, safety and environment: Explicit guidance to manage solvent emissions during application/curing and possible increased fumes/gases during welding/cutting. Emphasises worker protection and environmental controls (clause 5).
- Normative references: Part 1 directs users to specialized test procedures in related parts:
Practical applications - who uses this standard
- Primer manufacturers / suppliers: Use for R&D, new product development and production quality control to ensure consistent weldability performance.
- Fabricators and welding engineers: Reference when selecting or approving shop-primed steels for structural fabrication and specifying welding procedures.
- Procurement & contract authors: Include as a contractual reference for primer delivery requirements and acceptance testing.
- Quality assurance teams and customers: Conduct acceptance testing or comparative evaluations between primers or welding procedures.
- Health & safety officers: Apply the standard's environmental and personnel protection guidance when testing or implementing shop-primed materials.
Note: Some comparative or production-oriented tests are not intended for contractual acceptance; consult Part 1 guidance and the specific test parts (2–4) for suitability.
